Hi, I have a Problem using find with a serializeable CMP field. (and hope someone here can give me a hint). ------------------- I'm using J2EE 1.3.1 Sun RI and ran into this problem:
I have a serializeable class as a CMP Field (Permission) and want to Do a findByPermission EJB query. (example code below). Things I have checked: - The dependant class in Serializeable (EJB SPEC 2.0 10.3.3) and has a new 'equals' method - find Parameter is of the same class as CMP field as required for the = operator (SPEC 2.0 11.2.10) --------- EJB QL Statement ------------ SELECT OBJECT(perm) FROM PermissionSchema as perm WHERE perm.permission = ?1 --------- EJB QL Statement ------------ But still the RI Deployment Tool complains (while generating SQL): ---- Invalid type of expression (perm.permission = ?1) ---- Any Ideas ?? ----------- Java example code ----------- public abstract class PermissionBean implements EntityBean{ public abstract void setPermission(Permission perm); public abstract Permission getPermission(); [...] } public interface PermissionHomeLocal extends EJBLocalHome { [...] public PermissionLocal findByPermission(Permission permission) throws FinderException; } public class Permission implements Serializable { public final static Permission CREATE_USER = new Permission("Create User", "Allows User Creation"); final private String name; final private String description; private Permission (final String name, final String description){ this.name = name; this.description = description; } public String getName() { return this.name; } public String getDescription() { return this.description; } public boolean equals(Object obj) { if (obj instanceof Permission) { Permission perm = (Permission) obj; return this.name.equals(perm.getName()); } return false; } } ----------- Java example code ----------- Ciao Jens Skripczynski -- E-Mail: skripi-lists(at)myrealbox(dot)com "They say if you play the Windows 2000 CD backward, you can hear satanic words."
